In a shared webhosting environment, you often do not have access to the unix command to display your apache modules (apachectl -M).

This is a way to work around it:
The htaccess file must contain a line to display each apache module we want to check:

        <IfModule mod_access.c>
         Header set x-mod_access true
        </IfModule>

        <IfModule mod_access_compat.c>
         Header set x-mod_access_compat true
        </IfModule>

Then the html page performs an xml-http request to itself, and examines the response headers to see which apache modules we have identified on the server.
